Egyptian fraction

Egyptian fractions are a type of fraction used in ancient Egypt. They are different from other fractions because they can only be written as sums of fractions with a denominator of a power of two (e.g. 2, 4, 8, 16, 32, etc.). For example, 1/3 can be written as 1/2 + 1/4. This type of fraction was used a lot in ancient Egypt and was very easy to calculate.
